/* FILE: randStompField.cpp   last change: 30-Jul-2013   author: Romeo Rizzi
 * This program generates a random mxn Stomp field of 3 values: 0,1,2.
 * The field is designed has to be devided into several regions by enforcing
 * the presence of k-spaced stripes
 * Usage syntax:
 *   > randStompField.cpp m n k seed
 *
 * 
 * Usage example:
 *   > randStompField 10 10 3 777
